Abstract
An electronic governor for controlling the speed of one of two coupled prime movers wherein signals corresponding to wheel speeds of each of the two prime movers are compared to produce an error signal for controlling an actuator on one prime mover. The speed of the controlled prime mover may be abruptly reduced where the error signal exceeds a pre-determined threshold value. Monitoring means generally comprise digital circuitry, while control of the actuator is primarily analog acting through a servo loop containing a throttle position sensing device on the master prime mover, the error signal generating device and a throttle control device for the controlled prime mover.
